"Portrait of William Pitt, 1st Earl of Chatham" by Jean André Rouquet at the Victoria and Albert Museum, London - More commonly known as William Pitt the Elder (to distinguish him from his son William Pitt the Younger), this was the British Secretary of State during the Seven Years War and many victories have been attributed to his policies. This is why, for instance, when the British took Fort Duquesne from the French, they renamed it Fort Pitt - now the city of Pittsburgh, Pennsylvania.

William Pitt, later known as "Pitt the Elder", painted by William Hoare in 1754. This was the year he married Lady Hester Grenville.

John Pitt, 2nd Earl of Chatham, by George Romney, scanned from 'House of Pitt' by Sir Tresham Lever (1947). This is the portrait on which Jacqui Reiter's excellent drawing is based (http://pinterest.com/pin/41236152808369651). It hangs, or used to hang, at Chevening, formerly the home of William Pitt's biographer Earl Stanhope.

William Pitt the Younger

William Pitt engraved by John Jones, 1789, after the Romney portrait (which explains why he looks so handsome!) He's wearing his Chancellor's robes, and his right hand rests on a paper entitled "Regency Bill", meaning this print was produced on the back of the recently concluded Regency crisis (1788-89). This represents Pitt at the high point of his career. With the French revolution just around the corner, things were never again to be so rosy for him as at this precise moment.

One of the two main characters, William Pitt the Younger (1759-1806). Here portrayed by George Romney in about 1783, when he was 23/4. Incredibly he was probably already a cabinet minister when this portrait was painted.

When William the Conqueror seized control of England in 1066, he ordered the construction of several forts on the Thames to defend London against attack. The most famous was the Tower of London, pictured here in the 1400s.

"Portrait of Captain Sir William-Peer Williams, Bt., of the 16th Light Dragoons" by Allan Ramsay (1759) at the Courtauld Gallery, London - I'm actually really excited to see this, because one of my favourite historical fiction series (the "Jack Absolute" series by C.C. Humphreys) has the protagonist serving in the 16th Light Dragoons during the Seven Years War. I've never seen a portrait of an officer from there before, so now I'm definitely stoked.

1783-1784 British Portrait medallion of William Pitt the Younger at the Museum of London, London - From the curators' comments: "William Pitt the Younger became the youngest prime minister ever at the age of 24. He had only entered Parliament in 1781....Pitt remained in office continuously until 1801, a period which saw the French Revolution, the start of the Napoleonic Wars and the Act of Union between Britain and Ireland."

John Kitts Birth: May 7, 1762 Death: Sep. 18, 1870 He was born at Bloody Run, in Bedford County, Pa., in 1762, and is, therefore, now in the one hundred and fifth year of his age! In 1776, when fourteen years of age, he was a member of the First Pennsylvania Regiment of the Revolutionary War. He was in the battle of Yorktown, and occupied at one time the position of errand boy or messenger to Washington and Lafayette.

From the website: "William Pitt the Younger is dressed in a dark blue coat with brass buttons and a white neckcloth. He also has powdered hair. This portrait of the former Prime Minister is copied from a work by Gainsborough Dupont, the nephew of Thomas Gainsborough. It is one of numerous portraits of Pitt by Dupont, which are all thought to be based on an earlier, original, painted by Gainsborough himself. Gainsborough’s original work is now untraced."

This is the first known photograph of the American flag taken on June 21, 1873. The flag was flown over Fort McHenry in Baltimore, Maryland during an infamous battle between the British and the United States during the War of 1812 that inspired witness Francis Scott Key to pen "The Star-Spangled Banner."
